This page is for collecting evidence about Namespaces in XML not being helpful.
Bugs caused by Namespaces
- Redeclaring a namespace breaks
- Prefix difference breaks
- Prefix difference breaks
- Wrong prefix used causing bad expansion
- Feed aggregators failing with prefixed XHTML elements
- Declared prefix and used prefix differ
- RDFa used without declaring prefix
- Hard-wired prefix
Wrong documentation about Namespaces
- “90% of the technical questions” writes the O’Reilly XForms book author
- “Experience shows XML namespaces can be a common cause of confusion”
- “If there is any one of the W3C's family of XML specifications, that has caused me the most grief, XML Namespaces is probably it.” writes the Lead Developer of MSXML and System.Xml
- “I have a picture that made the audience at the session gasp in disbelief.” (Picture showing lots of namespace declarations.)
